If your ConfTool installation uses
Pro Forma Invoices (without an invoice number) before generating regular invoices (with an invoice number),
an
additional step is required to create two invoices with different billing addresses for a single participant.
First, go to the
List of All Registrations for Participation:
Overview => User and Participant Management => List of All Registrations for ParticipationSearch for the participant’s registration and
confirm the registration (see image 5).
This will convert the pro forma invoice into a regular invoice with an invoice number.
You can then proceed with the process described above.
